Action Steps

The shaded area from trees or landscape features is calculated based on the average shade provided at 10 a.m., 12 p.m., and 3 p.m. on the summer solstice. If vegetation is new, calculate the anticipated shading that will be provided after five years.

Assess your project site to determine if any of the credit compliance options are feasible. The four options are: 

Generate building floor plans highlighting line of sight to the outdoors and compliant floor areas for all regularly occupied spaces.

Confirm that lines of sight calculated using building floor plans are not obstructed at a "seated eye level" of 42 inches.

Using building floor plans, determine the percentage of regularly occupied spaces with direct line of sight to the outdoors. 

Calculate the total compliant area and overall percentage of compliant, regularly occupied space.

Record field measurements on building floor plans.

Take field measurements, using a handheld light meter, of the illumination levels in all regularly occupied spaces.

Assess whether your project complies with rules pertaining to ceiling obstructions, light redirection, and glare control.

Run calculations for each regularly occupied space to determine compliant areas.
